Food Security Status, Nutrient Intake At The Beginning And End Of The Monthly Resource Cycle, And Body Mass Index In Female Food Stamp Recipients, Caroline C. Burke

LSU Master's Theses

Diets are typically poorer and risk of chronic disease (e.g. obesity) is greatest in low-income populations. Food security status, nutrient intake, and Body Mass Index were assessed in 64 female food stamp recipients in Southeast Louisiana. One 24-hour dietary recall was collected at the beginning of the month (Day 1) and one at the end of the month (Day 2). Food security status was: 29 food secure (FS), 26 food insecure (FIS), and nine food insecure with hunger (FISH). Sixty-two % (n=39) of our study participants were obese. Mean % energy from protein (p=0.03); total fat (p=0.029), % saturated fatty …

The Influence Of Transdermally Administered Fentanyl On Isoflurane Requirements In Normothermic And Hypothermic Dogs, Diane Wilson

LSU Master's Theses

Intraoperative reductions in serum fentanyl levels in dogs with induced moderate hypothermia and transdermal fentanyl patches (TDF) in place has been documented. The impact of such reductions has not been evaluated nor has the anesthetic sparing effect of the TDF. Reductions in serum levels may be the result of either a decreased uptake of fentanyl from the dermal depot, or a biophase shift. The objective of this investigation was to determine whether the minimum alveolar concentration (MAC) of isoflurane was altered in the presence of TDF in normothermic and hypothermic dogs. Six mature, healthy, mixed breed dogs were anesthetized on …

Multiscale Strain Analysis, Timothy Donald Breitzman

LSU Doctoral Dissertations

The mathematical homogenization and corrector theory relevant to prestressed heterogeneous materials in the linear-elastic regime is discussed. A suitable corrector theory is derived to reconstruct the local strain field inside the composite. Based on this theory, we develop an inexpensive numerical method for multi scale strain analysis within a prestressed heterogeneous material. The theory also provides a characterization of the macroscopic strength domain. The strength domain places constraints on the homogenized strain field which guarantee that the actual strain in the heterogeneous material lies inside the strength domain of each material participating in the structure.

Comparative Studies Of Sperm Cryopreservation Of Diploid And Tetraploid Pacific Oysters, Qiaoxiang Dong

LSU Doctoral Dissertations

This dissertation addressed comparative studies of sperm cryopreservation of diploid and tetraploid Pacific oysters, Crassostrea gigas, with an emphasis on the development of standardized and optimized protocols. This includes comparative ultrastructural differences between sperm from diploid and tetraploid oysters, methods for the rapid estimation of sperm concentration, optimization of cryopreservation, and evaluation of the mechanisms for sperm agglutination (formation of clumps or elongated "noodles") in thawed samples. Currently, cryopreserved sperm has not been commercialized in any aquatic species, and standardization and optimization could greatly benefit the potential commercialization of its use. In oysters specifically, cryopreserved sperm from tetraploids would facilitate …

The Asymptotic Z-Transform, Scott Jude Champagne

LSU Master's Theses

Sequences of numbers and transformations from sequences to functions have been studied extensively, including the multiplication of two sequences through convolution and the equivalent multiplication of functions. The focal points of this thesis are the convolution field of causal sequences and their Z-transforms. Classically, the treatment of the Z-transform has been limited to those causal sequences for which the power series has a nontrivial radius of convergence. In this thesis it is shown that the Z-transform can be extended to all causal sequences without compromising any of the operational properties of the classical Z-transform.

Proliferating cell nuclear antigen …

Mesoscopic Simulation Of Grain Boundary Diffusion Creep In Inhomogeneous Microstructures, Kanishk Rastogi

LSU Master's Theses

At high temperatures, stresses well below the material’s tensile yield strength can induce permanent deformation over a period of time. This time-dependent progressive deformation of a material at constant stress is called Creep and is observed in both crystalline and non-crystalline solids. The principal deformation processes contributing to creep deformation are slip, sub-grain formation and grain-boundary sliding. Mechanisms involving creep of crystalline materials involve either dislocation motion or diffusional flow of atoms or both. Extensive studies have been done to ascertain the creep mechanism in various regimes of temperature and applied stresses. At low stresses and high temperatures, grain boundary …

Deposition Of Carbon Layers From Cyclohexane By Thermal Chemical Vapor Deposition, Bharath Thiruvengadachari

Cyclohexane (C6H12) hydrocarbon is the precursor material used as the source of carbon. A 20% Cu- 80% Ni alloy, deposited by RF magnetron sputtering and annealed at the growth temperature either in an argon flow or in 10% hydrogen-90% argon flow, is used as a catalyst prior to carbon film deposition by CVD. The CVD temperature is varied between 550 0C and 800 0C. The Cu-Ni …

Weight Concern And Smoking In Children, Darla E. Kendzor

LSU Master's Theses

Studies have shown that weight concern is prevalent in children and that many children believe smoking can be used to control appetite and weight. However, little is known about the impact of the combination of these factors on smoking initiation in children. Initial research has indicated that weight concern predicts smoking initiation in adolescents, but these studies have not addressed the role of weight control outcome expectancies. The purpose of this study was to prospectively investigate the relationship between weight concern and smoking initiation, and to evaluate weight control outcome expectancies as a moderator of this relationship in children. Cross-sectional …

Martin Heidegger's Phenomenology And The Science Of Mind, Charles Dale Hollingsworth

LSU Master's Theses

Phenomenology and cognitive science present two very different ways of looking at mental activity. Recently, however, there have been some attempts to incorporate phenomenological insights and methods into cognitive science, drawing especially on the works of Martin Heidegger. The purpose of this thesis is to determine if a useful combination of cognitive science with Heidegger’s phenomenology is possible, and to determine the form such a combination might take. This thesis begins with a brief overview of the field of cognitive science, and of some of the problems within the field that might benefit from a phenomenological analysis. It then reviews …

Fairness And Farmland Preservation: A Response To Professor Richardson, Mark W. Cordes

Faculty Articles, Papers, and Other Scholarship

In a recent article published in this Journal, Professor Jesse Richardson attempted to refute the arguments proposed by myself and others that support the fairness of downzoning land without compensation to property owners. Central to most farmland preservation efforts is agricultural zoning, which typically involves downzoning farmland to agricultural use, precluding more intensive development. Part IV will briefly comment on the role compensatory programs like PDRs and TDRs should play in effective farmland preservation programs. This is true even if downzoning results in substantial diminution of land values, which means that local governments can pursue farmland preservation by putting the …

Semantic Classification Of Rural And Urban Images Using Learning Vector Quantization, Prakash Thulasiraman

LSU Master's Theses

One of the major hurdles in semantic image classification is that only low-level features can be reliably extracted from images as opposed to higher level features (objects present in the scene and their inter-relationships). The main challenge lies in grouping images into semantically meaningful categories based on the available low-level visual features of the images. It is important that we have a classification method that will handle a complex image dataset with not so well defined boundaries between clusters. Learning Vector Quantization (LVQ) neural networks offer a great deal of robustness in clustering complex datasets. This study presents a semantic …

Comparative Analysis Of Conventional And Ici-Self-Cancellation Digital Video Broadcasting Transceivers, Khaled Z. Matarneh

LSU Master's Theses

Digital video broadcasting–terrestrial (DVB-T) is one of the important technologies in the communication area because of its capability of high data-rate multimedia transmission. Orthogonal frequency division multiplexing (OFDM) has been the backbone technique in the current DVB-T systems adopted by Europe and Japan. However, since the OFDM system is very sensitive to the frequency synchronization and phase errors, which will induce the intercarrier interference (ICI), the ongoing research has been dedicated to this ICI problem in the presence of the Doppler frequency drift and the fading channels. A means to deal with the ICI problem is called the ICI self-cancellation …

Export-Led Growth In Honduras And The Central American Region, Hermann Castro Zuniga

LSU Master's Theses

This thesis examines the validity of the export-led growth (ELG) hypothesis in Honduras and compares the Honduran experience to that of other Central American countries, specifically Costa Rica, El Salvador, Guatemala and Nicaragua. It further evaluates the ELG hypothesis for the agricultural sector of Honduras. The conceptual model incorporates exports into a Cobb-Douglas production function and formulates dynamic econometric models of real gross domestic product (GDP), real gross fixed capital formation (GFCF), labor and real exports for the 1970-2000 period. To test for the validity of the ELG hypothesis, Granger-causality was tested on the export coefficients of the growth equation …

A Hellenistic Masterpiece: The Medici Aphrodite, Angel D. Arvello

LSU Master's Theses

Numerous copies of both the Medici and Capitoline Aphrodite were produced in the Roman period. Judging only from the number of copies, it is generally accepted that the Capitoline was the most popular type followed by the Knidia and finally the Medici. First an examination of the copies, variants and quotations of each type is given to provide some background on the Medici and Capitoline. Next is a discussion of the dating of the pieces which has typically ranged from the fourth to the first centuries BC. An overview of a second century trend is presented to place both pieces …

Too Fast, Too Tight, Too Loud, Too Bright, David Martin Storlie

LSU Master's Theses

It is difficult to imagine that others do not perceive and react to the cultural stimuli as I do when dealing with everyday sensory situations. Unlike most, I have struggled with many different responses to commonplace sensory events during my life. A recent diagnosis of certain symptoms has helped to explain not only my lifelong reactions to sensory stimuli, but also the resulting environments I have created for myself in which I live and work. The four terms I use that most fully describe the affects of this condition are; too fast, too tight, too loud and too bright. Although …

Evaluation Of Helicobacter Hepaticus Bacterial Shedding In Fostered And Strategically Housed C57bl/6 Mice, J. Robin Crisler Roberts

LSU Master's Theses

The murine pathogen Helicobacter hepaticus has important confounding effects on research. Neonatal fostering has been studied in our laboratory for elimination of infection in mice. The purpose of our study was to examine fostering of pups from experimentally infected dams in male-absent parturition, and to determine the significance of gender and time on quantity of bacterial colonization in the cecum and feces of C57BL/6 mice. Approximately 20 C57BL/6 mice were fostered per day from one to four days of age. None of the C57BL/6 pups tested positive by PCR in fecal or cecal samples through four days of age. This …

Cooperative Federalism And Natural Resources Law, Robert L. Fischman

Articles by Maurer Faculty

Cooperative federalism describes an arrangement under which a national government induces coordination from subordinate jurisdictions, such as states and tribes, through incentives rather than requirements. In environmental law, cooperative federalism highlights the divide between pollution control and resource management. This article examines the divide from both sides.

Even though almost all of the environmental law commentary on cooperative federalism focuses exclusively on the pollution control side, the basic elements of cooperative federalism can be combined in a wider variety of forms than are recognized by most pollution control programs or scholarship. This article reviews the ways in which resource management …

Evaluation Of Beauveria Bassiana And Host Plant Resistance For The Management Of Rice Stink Bug In Rice Agro-Ecosystem, Dilipkumar Thakorbhai Patel

LSU Master's Theses

Isolates of Beauveria bassiana (Balsamo) Vuillemin were tested for biological control of rice stink bug, Oebalus pugnax (Fab.), in the laboratory, in small-plot field experiments compared with conventional insecticides, and in a large-plot experiment to determine the spread and persistence of the fungus. The soil-derived isolate LRC28 was more virulent to O. pugnax adults than the rice stink bug-derived isolate RSB in a laboratory experiment. The fungal isolates did not differ from one another in reducing insect numbers or in infecting rice stink bugs in the small-plot experiments. A single application of B. bassiana reduced rice stink bug nymphs on …

Use Of Orthogonal Arrays, Quasi-Monte Carlo Sampling And Kriging Response Models For Reservoir Simulation With Many Varying Factors, Subhash Kalla

LSU Master's Theses

Asset development teams may adjust simulation model parameters using experimental design to reveal which factors have the greatest impact on the reservoir performance. Response surfaces and experimental design make sensitivity analysis less expensive and more accurate, helping to optimize recovery under geological and economical uncertainties. In this thesis, experimental designs including orthogonal arrays, factorial designs, Latin hypercubes and Hammersley sequences are compared and analyzed. These methods are demonstrated for a gas well with water coning problem to illustrate the efficiency of orthogonal arrays. Eleven geologic factors are varied while optimizing three engineering factors (total of fourteen factors). The objective is …

The Effects Of Aluminum Concentration On Growth Responses In Six Spartina Alterniflora Genotypes, Daniel Farrell Becker

LSU Master's Theses

Elevated soluble aluminum concentrations can adversely affect plant growth. During a drought, wetland soils may experience higher than normal soluble aluminum due to the oxidation of metal sulfides and resulting decreases in pH, which mobilizes metallic cations. Louisiana coastal salt marshes were subject to a record-setting drought in the winter and spring of 2000 which was coincident with the die-off of large expanses of salt marsh, termed " brown marsh ". Spartina alterniflora was the primary plant species affected. However, because some individuals within large areas of die-off survived the brown marsh event, they may have been the more resistant …

Effect Of Multiuser Interference On Subscriber Location In Cdma Networks, Rohit Sharma

LSU Master's Theses

The last few years have witnessed an ever growing interest in the field of mobile location systems for cellular systems. The motivation is the series of regulations passed by Federal Communications Commission, requiring that wireless service providers support a mobile telephone callback feature and cell site location mechanism. A further application of the location technology is in the rapidly emerging field of intelligent transportation systems, which are intended to enhance highway safety, location based billing etc. Many of the existing location technologies use GPS and its derivatives which require a specialized subscriber equipment. This is not feasible for popular use, …

Augmented Watermarking, Kiranmayi Penumarthi

LSU Master's Theses

This thesis provides an augmented watermarking technique wherein noise is based on the watermark added to the watermarked image so that only the end user who has the key for embedding the watermark can both remove the noise and watermark to get a final clear image. The recovery for different values of noise is observed. This system may be implemented as a basic digital rights management system by defining a regime of partial rights using overlaid watermarks, together with respectively added layers of noise, in which the rights of the users define the precision with which the signals may be …

Experimental And Numerical Study Of Feeding Channel In Proton Exchange Membrane Fuel Cell, Abul Bashar Mahmud Hasan

LSU Master's Theses

The performance of a Proton Exchange Membrane Fuel Cell (PEMFC) using different feeding configurations has been studied, with a focus on the water flooding due to electrochemical reaction. Feeding channel or Bipolar plate in Proton Exchange Fuel Cell is a dominating part. As feeding channel keeps direct contact with the gas diffusion layer, it helps efficiently supplying fuel and air into the gas diffusion layer for efficient production of electricity. Experimental data have been taken at hydrogen flow rates of 20,40,60,80,100 sccm for various bipolar plate arrangements. Three bipolar plates, namely serpentine, straight channel and interdigitated designs, were arranged in …

Efficacy Of Modified Parent Training To Facilitate Expressive Language Of Children With An Expressive Language Delay, Marie Henderson

This study aimed to study the efficacy of a modified parent-training program on parents’ use of language facilitative techniques. The training method employed a handout and discussion of the facilitative techniques and how they could be incorporated into play time with the children. Participants included 4 parent-child dyads recruited from a school for children with language delays. Effectiveness of the training was determined by taking data on parent and child behaviors from tape recordings of parent-child play interactions that occurred in each family’s home. Results showed that parents were able to use the procedures during baseline and maintained relatively stable …

Effect Of Estradiol-17b On The Gonadal Developemnt Of Diploid And Triploid Female Eastern Oysters, Roberto Quintana

LSU Master's Theses

Declines in annual oyster landings and problems associated with seasonal reduction of oyster meat yields have increased interest for development of techniques to produce oysters with enhanced growth characteristics. Research interest has been focused on developing improved lines by induction of polyploidy. The goal of the present study was to evaluate the enhancement of gonadal development of triploid oysters, by the use of the hormone estradiol 17-â (E2) to produce viable eggs for the development of tetraploid broodstocks. Previous studies with the Pacific oyster, Crassostrea gigas, have shown: (1) the need to use the larger eggs of triploid females to …
